Title: Cooling method for rolling roll
Inventor: TAKAHASHI TSUTOMU
IPC: B21B27/10
Filed: 1989-06-20
Abstract: PURPOSE:To prevent the change in the thermal crown quantity of rolling rolls by forming the flow of water which flows in a laminar state on the roll surfaces, injecting pressure water toward this water flow and adjusting the spraying rate of the pressure water according to the quantity of the heat received in the transverse direction of the rolls. CONSTITUTION:Many injection nozzles 13 which inject the pressure water 13a to the laminar flow in the direction perpendicular thereto are provided in order to destroy boundary layers. The nozzles 13 are divided transversely to plural sets and are opened and closed by valves 14. The opening and closing of the valves 14 are executed by computing the heat load quantity in the transverse direction on the rolling rolls 1 by using a computing device 15 in accordance with rolling conditions (temp., etc.) and a rolling speed, rolling load, etc., as rolling information and by applying opening and closing commands to the respective valves 14 in the transverse direction according to the computed heat load quantity. The ease and accuracy of the adjustment of the cooling capacity are improved in this way even if the roll diameter changes. Since the smaller volume of the pressure water to be used is necessitated, the fine adjustment is possible and the responsiveness of the control is improved.

Title: Air-hammer excavating device and method
Inventor: MIZUNO YOSHIFUMI
IPC: E21B4/14
Filed: 1993-06-28
Abstract: PURPOSE:To prevent the diffusion of dust generated from slime, and to obviate the scattering of slime by discharging slime through a discharge passage formed in a hammer case. CONSTITUTION:A hammer case 60 is formed in the same diameter as the outside diameter of a bit 58, and disposed on the same axis as an air hammer body 56.

Title: Inspection method of semiconductor element
Inventor: KOBORI YOSHIO
IPC: H01L21/66
Filed: 1977-12-28
Abstract: PURPOSE: To inspect durability against stress at the time of soldering mounting by applying mechanical tension to a lead-mount type semiconductor element.  
     CONSTITUTION: Tension is applied to leads 4 and 5 of the element to rise the temperature of leads or its ambient temperature by stages. When the temperature reaches the softening that of resin 3, the tension is applied as shearing stress between pellet 1 and leads 4 and 5. If the tension is large, the pellet and leads are sheared mutually to cause a crack, so that a characteristic defect can be discriminated. When the temperature reaches the softening or fusing temperature of soldering material 2, the shift or gap of the fusion-bonded surface between the pellet and leads is made and a forward voltage drop increases, thereby making it possible to discruminate a defect.
